Ingredients

• 2 cups all-purpose flour
• 1.5 teaspoons baking powder
• 0.5 teaspoons baking soda
• 0.5 teaspoons salt
• 3 large ripe bananas
• 0.5 cups butter, softened
• 1 cup granulated sugar
• 0.5 cups brown sugar, packed
• 2 large eggs
• 1 teaspoons vanilla extract
• 0.5 cups buttermilk
• 1 cup softened butter (for frosting)
• 4 cups powdered sugar
• 2 teaspoons vanilla extract (for frosting)
• 2 tablespoons milk

Directions

Step 1

Preheat the oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.

Step 2

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

Step 3

In a separate bowl, mash the bananas until smooth. Set aside.

Step 4

In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together until light and fluffy, about 2-3 minutes.

Step 5

Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.

Step 6

Blend the mashed bananas into the wet ingredients until fully combined.

Step 7

Alternate adding the dry ingredients and buttermilk to the banana mixture, beginning and ending with the dry ingredients. Mix until just combined; do not overmix.

Step 8

Evenly divide the batter between the prepared cake pans and smooth the tops.

Step 9

Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

Step 10

Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.

Step 11

To make the buttercream frosting, beat the softened butter in a large bowl until creamy.

Step 12

Gradually add the powdered sugar, one cup at a time, mixing well after each addition.

Step 13

Add the vanilla extract and milk, and beat on high speed until the frosting is smooth and fluffy. Add more milk if a thinner consistency is desired.

Step 14

Once the cakes are completely cooled, spread a layer of buttercream frosting on top of one cake layer. Place the second cake layer on top and frost the entire cake.

Step 15

Slice, serve, and enjoy your delicious banana cake with buttercream frosting!
